Abstract

A permanent biocompatible material for soft tissue reinforcement. The biocompatible material comprises a smooth and round finely divided substantially spherical biocompatible ceramic particles, close to or in contact with each other, which provides a scaffolding structure or structure for autologous tissue, three-dimensional free positioning, in The augmentation site grows soft tissue without scars. The reinforcing material can be uniformly suspended in a biocompatible absorbable smooth gel carrier comprising a polysaccharide. It is used to improve the delivery properties of reinforcement materials injected into the tissue site where reinforcement is desired. Augments are particularly useful for strengthening the urethral sphincter, treating urinary incontinence, filling soft tissue voids, creating soft tissue blisters, treating unilateral vocal cord paralysis and for breast implants. It can be injected subcutaneously, intradermally or can be implanted.

Description

field of invention

[0001] The present invention relates to a biocompatible material for reinforcing soft tissue, and more particularly, the present invention relates to a urethral sphincter reinforcing material for treating incontinence, for filling soft tissue voids or creating soft tissue blisters; for breast implants and for Biocompatible material for soft tissue augmentation in the treatment of unilateral vocal cord paralysis. The invention also relates to a gel carrier for the biocompatible composition. Background technique

[0002] In the practice of plastic and reconstructive surgery, many biocompatible materials have been proposed for use in augmenting soft tissues, examples of which are collagen, gel beads, natural or synthetic materials such as polytetrafluoroethylene, silicone rubber, etc. Polymer beads and various hydrogel polymers such as polyacrylonitrile-polyacrylamide hydrogels.

[0003] Typically, the biomaterial is injected via an injectable composition c...
